Time Spy Extreme is a new 4K DirectX 12 benchmark test, and it's coming to 3DMark Advanced and Professional Editions on October 11. You won't need a 4K monitor to run it, though you will need a GPU with at least 4 GB of dedicated memory. With its 4K UHD rendering resolution, Time Spy Extreme is an ideal benchmark test for the latest high-end graphics cards. The CPU test is three times more demanding, redesigned to let processors with 8 or more cores perform to their full potential.
